TO'ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES H. PERKINS, of the city and county of Providence, in the State of Rhode Island,have invented a new and useful Improvement in Toe-Caikins Yor'Horse-Shns; and I tic-hereby declare" that the following specification, taken in connection with the drawings making a part of the same, is :a full, clear, and exact description thereof. Q

Figure 1 is a view in perspective.

Figures 2 and 3 are views in section upon the lines a Z and c 01 respectively.

The invention herein described is an improvement upon the article of manufacture which is the subject of the Letters Patent granted to me, April 9, A. D. 1861. In that invention, the toe-calkin is furnished with one or more tapering steel spurs, placed midway between the extremities, or nearly so'. In thepresent case,-instea1l of employing one or more taperingspurs, located in the line of the longitudinal axis of the calkin,'I provide the calkin with two chisel-edged tonons or Spurs, 6 6-, whose facesare opposite to each other, and parallel with the axis of the calkin. The length of these tenons or spurs should he, to obtain tlie best advantage'from their use, about one-third of the entire length of the calkim'.

The advantage which the form and location of these chisel-edged tenons induce over the pyramidal spurs described in the patent referred to is, that additional strength is given to the welded joint between the calkin and the shoe at the point of the toe where it is most exposed to shocks as the foot of the horse strikes the ground.

. I do not claim broadly a. toe-calkin for horse-shoe with holding-spurs, but

What I do claim as my invention, and desire to secure by Letters Patent, is-- A toe-calkin for horse-shoes, furnished with chisel-edged-tenons or spurs b b, set opposite to each other, and with their faces parallel with each other" and with the longitudinal axis of the calkin, substantially as described,

for the purposes specified.

CHARLES H. PERKINS.
